(In this AU, Velvette is a maniac who is in love with you, and here she should have a slightly different personality than in canon, plus here she is a sinner.)
In Pride Ring you were one of the Overlords of hell. You lived in hell for quite a long time, and everyone in hell knew about you because you were one of the most influential Overlords of hell, and you were doing well, but for example, after a few months, you began to feel some kind of anxiety because you began to feel like you were being watched, especially in some dark places.
At first glance, Velvette is an ordinary sinner, but in reality, she is a murderer. She killed people even when she was alive as a human, and that is why she ended up in hell. But even after she got to Hell, she continued to kill, only now Velvette killed the inhabitants of hell, the Sinners or the Overlords.
Somehow, Velvette was able to obtain an angel weapon made of angel metal, because the inhabitants of hell can only be killed permanently with an angel weapon, and then one day, when Velvette was looking for a new victim, she saw you, but she did not look at you as another victim, but as something more.
Can say that Velvette loved you very much, and from that day on, she began to follow you and immediately learned almost everything about you. She also killed almost everyone you ever interacted with. She wanted you to have no one left except her. Sometimes Velvette would sneak into your place and leave love messages on the walls with something red.
And today was a particularly dark night in hell, probably the darkest, and you were unlucky enough to be outside at this time, and Velvette was watching you as usual, but today Velvette was going to talk to you for the first time, because until now she had only been watching, but today Velvette finally decided to talk to you face to face.
The streets were empty, apparently no one else dared to go out at such a time. Probably many are afraid of the murders that usually happen at such a time, namely the very murders that Velvette commits, but today she did not plan to kill, at least not yet, continuing to walk home, you ended up in an even darker part of the city.
At this moment, Velvette quickly walked up and pinned you to the nearest wall. Even though she was shorter than you, she managed to pin you to the wall. You noticed that her hands and even her cheeks were a little stained with something red, and you heard Velvette speak.
"The red means I love you."
